2022-02-18drm/i915: Make the pipe/output CSC register writes locklessVille Syrjälä1-40/+40
The pipe/output CSC register writes don't need to be locked since all the registers are suitably isolated to their own cachelines. So eliminate the locks to reduce the overhead during the vblank evade critical section.

2022-02-18drm/i915: Move PIPE_CHICKEN RMW out from the vblank evade critical sectionVille Syrjälä1-3/+5
We don't want any RMWs in the part of the commit that happens under vblank evasion. Eventually we want to use the DSB to handle that and it can't read registers at all. Also reads are just slowing us down needlessly. Let's move the whole PIPE_CHICKEN stuff out from the critical section since we don't have anything there that needs to be syncrhonized with other plane/pipe registers. If we ever need to add such things then we have to move it back, but without doing any reads. TODO: should look into eliminating the RMW anyway...

2022-02-18drm/i915/display/tgl+: Implement new PLL programming stepJosé Roberto de Souza8-13/+65
A new programming step was added to combo and TC PLL sequences. If override_AFC_startup is set in VBT, driver should overwrite AFC_startup value to 0x0 or 0x7 in PLL's div0 register. The current understating is that only TGL needs this and all other display 12 and newer platforms will have a older VBT or a newer VBT with override_AFC_startup set to 0 but in any case there is a drm_warn_on_once() to let us know if this is not true. v2: - specification updated, now AFC can be override to 0x0 or 0x7 - not using a union for div0 (Imre) - following previous wrong vbt naming: bits instead of bytes (Imre) BSpec: 49204 BSpec: 20122 BSpec: 49968 BSpec: 71360 Cc: Imre Deak <imre.deak@intel.com> Cc: Jani Nikula <jani.nikula@intel.com> Reviewed-by: Imre Deak <imre.deak@intel.com> Signed-off-by: José Roberto de Souza <jose.souza@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220216134059.25348-1-jose.souza@intel.com
2022-02-18drm/i915: Disconnect PHYs left connected by BIOS on disabled portsImre Deak1-6/+20
BIOS may leave a TypeC PHY in a connected state even though the corresponding port is disabled. This will prevent any hotplug events from being signalled (after the monitor deasserts and then reasserts its HPD) until the PHY is disconnected and so the driver will not detect a connected sink. Rebooting with the PHY in the connected state also results in a system hang. Fix the above by disconnecting TypeC PHYs on disabled ports. Before commit 64851a32c463e5 the PHY connected state was read out even for disabled ports and later the PHY got disconnected as a side effect of a tc_port_lock/unlock() sequence (during connector probing), hence recovering the port's hotplug functionality.

Registers that exist within the MCH BAR and are mirrored into the GPU's MMIO space are a good candidate to separate out into their own header.

Get rid of the inflexible bigjoiner_linked_crtc pointer thing and just track things as a bitmask of pipes instead. We can also nuke the bigjoiner_slave boolean as the role of the pipe can be determined from its position in the bitmask. It might be possible to nuke the bigjoiner boolean as well if we make encoder.compute_config() do the bitmask assignment directly for the master pipe. But for now I left that alone so that encoer.compute_config() will just flag the state as needing bigjoiner, and the intel_atomic_check_bigjoiner() is still responsible for determining the bitmask. But that may have to change as the encoder may be in the best position to determine how exactly we should populate the bitmask. Most places that just looked at the single bigjoiner_linked_crtc now iterate over the whole bitmask, eliminating the singular slave pipe assumption.

2022-02-15drm/i915: Convert for_each_intel_crtc_mask() to take a pipe mask insteadVille Syrjälä2-19/+19
Often using pipes is more convenient than crtc indices. Convert the current for_each_intel_crtc_mask() to take a pipe mask instead of a crtc index mask, and rename it to for_each_intel_crtc_in_pipe_mask() to make it clear what it does. The current users of for_each_intel_crtc_mask() don't really care which kind of mask we use, but for other uses a pipe mask if better.

2022-02-11drm/i915: Clean up the bigjoiner state copy logicVille Syrjälä3-75/+108
Currently the bigjoiner state copy logic is kind of a byzantine mess. Clean it up to operate in the following manner during a full modeset: 1) master uapi -> hw state copy 2) master hw -> slave hw state copy And during a non-modeset update we do: 1) master uapi -> hw state light copy 2) master hw -> slave hw state light copy I think that is now easier to reason about since we never do any kind of master uapi -> slave hw state copy short circuit that could happen previously. Obviously this does now depend on the master uapi->hw copy always happening before the master hw -> slave hw copy, but that is guaranteed by the fact that we always add both crtcs to the state early, the crtcs are registered in pipe order (so the compute_config loop happens in pipe order), and the hardware requires the master pipe has to be lower than the slave pipe as well. And for good measure we shall add a check+WARN for this before doing the bigjoiner crtc assignment. v2: Fix uapi.ctm vs. hw.ctm copy-paste fail Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220204072049.1610-1-ville.syrjala@linux.intel.com Reviewed-by: Manasi Navare <manasi.d.navare@intel.com>
